A few things to keep in mind while completing this activity:

  1. Do not use the browser Back button or close or reload any exam windows during the exam.
  2. Do not close Packet Tracer when you are done. It will close automatically.
  3. Click the Submit Assessment button in the browser window to submit your work.

Assessment Objectives

  • Part 1: Build the Network
  • Part 2: Configure Initial Device Settings
  • Part 3: Configure Network Infrastructure Settings (VLANs, Trunking, EtherChannel)
  • Part 4: Configure Host Support

Introduction

In this Packet Tracer Skills Assessment (PTSA) you will configure the devices in a small network. You must configure a router, two switches, and two PCs to support both IPv4 and IPv6 connectivity. Your router and switches must also be managed securely. You will configure inter-VLAN routing, DHCP, Etherchannel, and port-security.
All of your tasks will be performed in PT Physical Mode. You will not be able to access the logical topology for this assessment. Network devices must be configured from a direct console connection.

Instructions

Part 1: Build the Network

  • a. Move the required devices into the equipment rack.
  • b. Place the PCs on the table.
  • c. Connect the devices according to the topology diagram.
  • Use Copper Straight-Through cable to connect all devices

    Turn on the devices PCs and Router

    Part 2: Configure Initial Device Settings

    All IOS device configuration must be made through a direct console connections.

    To show Console port on Switch, Right click Switch –> Inspect Rear –> Console port

    Step 1: Configure R1 Basic Settings and Device Hardening

    a. Configure basic settings.

    1. Prevent the router from attempting to resolve incorrectly entered commands as domain names.
    2. Configure the R1 hostname.
    3. Configure an appropriate MOTD banner.
    Router(config)#no ip domain lookup 
Router(config)#hostname R1
R1(config)#banner motd #Unauthorized Acess is Prohibited#

    b. Configure password security.

    1. Configure the console password and enable connections.
    2. Configure an enable secret password.
    3. Encrypt all clear text passwords.
    4. Set the minimum length of newly created passwords to 10 characters.
    R1(config)#line console 0
R1(config-line)#password ciscoconpass
R1(config-line)#login
R1(config-line)#exit

R1(config)#enable secret ciscoenpass

R1(config)#service password-encryption 

R1(config)#security passwords min-length 10

    c. Configure SSH.
    1) Create an administrative user in the local user database.

    • Username: admin
    • Encrypted Password: admin1pass

    2) Configure the domain name as ccna-ptsa.com
    3) Create an RSA crypto key with a modulus of 1024 bits.
    4) Ensure that more secure version of SSH will be used.
    5) Configure the vty lines to authenticate logins against the local user database.
    6) Configure the vty lines to only accept connections over SSH.

    R1(config)#username admin secret admin1pass

R1(config)#ip domain name ccna-ptsa.com

R1(config)#crypto key generate rsa
1024

R1(config)#ip ssh version 2

R1(config)#line vty 0 15
R1(config-line)#login local
R1(config-line)#transport input ssh 
R1(config-line)#exit
    Step 2: Configure router interfaces.

    a. Configure R1 with a loopback interface. Configure the loopback0 with IPv4 and IPv6 addressing according to the addressing table.

    R1(config-subif)#interface Loopback 0
R1(config-subif)#description Loopback
R1(config-subif)#ip address 209.165.201.1 255.255.255.224
R1(config-subif)#ipv6 address 2001:db8:acad:209::1/64
R1(config-subif)#ipv6 address fe80::1 link-local
R1(config-subif)#exit

    b. Configure Router Subinterfaces

    1. Prepare the router to be configured with IPv6 addresses on its interfaces.
    2. Use the information in the Addressing Table and VLAN Table to configure subinterfaces on R1:
      • Interfaces should be configured with IPv4 and IPv6 addressing.
      • All addressed interfaces should use fe80::1 as the link local address.
      • Use the VLAN table to assign VLAN membership to the subinterfaces.
    3. Be sure to configure the native VLAN interface.
    4. Configure descriptions for all interfaces.
